Photosensitive meds?

~Some medications can make people more susceptible to sunburns

The Concern -- The forecast says sun, but what does your drug label say? Sunshine lovers should know that certain medications can make them more susceptible to sunburn, a condition known as drug-induced photosensitivity.

The Cause -- The Food and Drug Administration explains that exposure to ultraviolet radiation from sunlight and, yes, even tanning booths, causes photoreactive agents in some drugs to undergo chemical changes that increase a person's vulnerability to light. Redness, blotching, itching, swelling and blistering can result from short-term exposure, and premature skin aging and skin cancer from long-term exposure. The degree of photosensitivity will vary among individuals.

The Culprits -- According to Lindsey Stephens, a pharmacist and director of professional services for Medicine Shoppe International, a franchiser of independent community pharmacies, the more commonly used drugs that can cause photosensitivity reactions include: ibuprofen and other nonsteroidal anti-inflammatory drugs (NSAIDs); certain antibiotics, including the tetracyclines and sulfa drugs; hydrochlorothiazide, a common diuretic used for high blood pressure; certain diabetes medications, like glyburide and glipizide; Retin-A, a topical acne and wrinkle medication; and microdermabrasion products and those containing alpha hydroxy acids.

The Counsel --To block the burn, Stephens advises patients to read their drug labels and consult with their pharmacist or doctor before going out in the sun. If you can't avoid the sun, lather up with sunscreen -- SPF 30 or higher -- with zinc oxide (the "micronized" form of this ingredient is less visible than the thick white stuff you may remember from childhood), making sure you cover your hands and feet, and wear protective clothing. "Everyone faces a risk of sunburn when going outside," Stephens said, "but those who are taking certain medications should be especially vigilant."
